Comment #19 on issue 2807 by hazelnu...@gmail.com: Change .unit and .mag to
proper methods and better names.

:) Ok.
Well it seems like we mostly agree on normalize, but what about magnitude
vs. norm?
I think .magnitude(self, p=2) is probably more suited for
engineers, .norm(self, p=2) more so for mathematicians/physicists, but I
can't see any strong argument for one vs. the other.
I vote for magnitude(self, p=2). For the quantities that are being dealt
with with in physics.mechanics, such as force, torque, velocity,
acceleration, it seems more natural to talk of their magnitude (i.e., "the
force had a magnitude of 10N" instead of "the force had a norm of 10N").
If you know what a norm is, you'll know that magnitude is a synonym for
it. I wouldn't expect the converse to be true, i.e., if you know what the
magnitude is, you might still not be familiar with the use of norm as a
synonym for magnitude, and you may very well not be familiar with all the
different types of norms that are out there.
